我试过Angular2 QuickStart。为了执行此操作，我使用了npm start。在它的第一次尝试它工作正常。但是在第二天，当我尝试使用npm start运行时，它会抛出这样的错误：

21 error Make sure you have the latest version of node.js and npm installed.
21 error If you do, this is most likely a problem with the angular-quickstart package,
21 error not with npm itself.
21 error Tell the author that this fails on your system:
21 error npm run build
21 error You can get information on how to open an issue for this project with:
21 error npm bugs angular-quickstart
21 error Or if that isn't available, you can get their info via:
21 error npm owner ls angular-quickstart
21 error There is likely additional logging output above.
22 verbose exit [ 1, true ]
我该如何解决这个问题？
答案 0 :(得分：0)
在QuickStart目录中打开 2 cmd windows 。
窗口＃1：
npm run build:watch
然后，
窗口＃2：
npm run serve
然后它将在浏览器中打开并按预期工作。
